Removing DVD drive ffro Mesh PC

Does anyone know the technique of how to remove my DVD drive from the tower case of my 1 year old Mesh PC. There doesn't seem to be any screws to undo so I am a bit lost!! I want to exchange it for a DVD writer.Thanks

it may not be screwed in as i have a case which uses sliders that clip into the removable drives and slide into a groove in the case

when you take the side off the case you should see where the drive is fixed to, there should be some screws noticable at the side of the drive holding the drive into the case, if you cannot see them.then it amy be possible you have a similar case to me,removing the front of the case off on mine reveals the clips that hold my drives in and you can squeeze the clips and slide the drive out from the case..make sure you have the wires dissconnected before you do this, i am only going by my case and that you havn't got any screws, so your setup may be slightly different
